Surgical Oncology
When your doctor says the word “cancer,” it’s natural to feel overwhelmed and apprehensive. The entire Allied Surgical Group team understands. We’re here for you, with the information you need to make smart decisions. We offer a friendly, supportive place to turn for the most advanced, comprehensive treatment options.
Our Surgical Oncologists specialize in surgical cancer treatment and are equipped to offer a full spectrum of diagnostic, early detection, surgery and post-surgery support services.
We’re in this fight together, and our doctors and support staff will do everything in their power to achieve success.
Collectively, our physicians diagnose and treat 90 percent of all breast cancer patients needing surgery at Morristown Memorial Hospital. Dr. Diehl also provides breast surgical services at Saint Clare’s Hospital in Denville and Dover. We have the most extensive experience in the state and feature minimally invasive sentinel node biopsy techniques, having introduced the technology in New Jersey in 1997.
Our surgeons are leaders in the field and utilize the least invasive techniques. We also specialize in breast conservation surgery. For patients who are not candidates for breast preserving therapy, we offer the most advanced mastectomy options available, such as skin-sparing mastectomies and immediate-tissue-transfer reconstruction.
Diagnostic services include ultrasound-guided breast biopsy, sentinel node biopsy and the minimally invasive stereotactic needle biopsy.
Allied Surgical Group offers specialty services for patients with solid organ malignancies. If you are diagnosed with any gastrointestinal, colon, liver, pancreatic, esophageal or stomach cancer, our surgeons are trained and experienced in removing these tumors.
For some patients, minimally invasive options such as laparoscopy or radio frequency ablation may be available. Every patient and treatment strategy is unique, and all your options will be thoroughly explained.
Allied Surgical Group offers comprehensive coordinated care for patients diagnosed with cancer of the head and neck, including endocrine malignancies such as thyroid and parathyroid tumors.
Over one million skin cancers will be diagnosed this year. With early detection, most can be successfully treated.
At Allied Surgical Group, our surgeons offer advanced skin cancer detection and treatment methods for treating melanomas, squamous cell carcinoma, basal cell carcinoma and sarcomas, including limb-function-sparing procedures and techniques that minimize scarring and deformity.
